Another key threat to our country’s security and resilience, which does not receive nearly enough attention, is climate breakdown. It is not just the environmentalists but the ambulance workers who say that, and the Joint Intelligence and Security Committee’s national security assessment itself says that ecosystem breakdown poses a clear threat to national security. The Committee on Climate Change has pointed out that we are woefully ill-prepared as a country for the effects of climate breakdown.

We urgently need to take more action to avoid causing climate change. Equally, we urgently need to take far more action to recognise the threat to our national security and resilience posed by the effects of climate breakdown. That was brought home to us in hugely clear terms last week, as we faced the second major heatwave of the last month or so. That heatwave led to record call-outs for the ambulance service—even more than under covid.

Does the hon. Member accept that there is a certain irony when the same people who are concerned about climate change and temperatures rising have campaigned for air conditioning to be taken out of buildings because of its energy consumption and carbon dioxide emissions? We cannot have it both ways, can we?

The Committee on Climate Change—the Government’s independent adviser—has set out repeatedly that these solutions are available and has set out the things that we need to put forward. The Committee has also set out repeatedly, as have any number of people over any number of years, the fact that the costs of inaction far exceed those of action. The hon. Member for Warwick and Leamington (Matt Western) made that point previously in relation to other security challenges, and it applies with knobs on to tackling the challenge of climate breakdown. Twenty years ago, Professor Nick Stern set out clearly that the costs of inaction far outweigh—many times over—the costs of action to address these risks. After 20 years of our heads collectively being in the sand as a country, we are reaping the whirlwind of that inaction.

We need to develop a comprehensive extreme heat strategy, a national drought plan and a farmer-led transition to climate-resilient food production. Our farmers are crying out for that support, and they too are on the frontline of the security and resilience challenges that the reality of climate breakdown places on us. We need to strengthen our transport infrastructure, energy infrastructure and water infrastructure. Last week, we heard about nuclear power stations going offline in France. Train companies were saying that nobody should travel unless it was a matter of life and death. Water shortages are becoming more and more frequent. The collective, long-term and strategic approach to tackling climate resilience must be a core plank of national security.

Tackling climate breakdown is not just an environmental issue but a central plank of security and national resilience. The costs of inaction far outweigh the costs of taking action now. Will the Minister commit to putting in place a national strategy? Will there be an individual identified in the Cabinet Office who leads on it? Does she recognise that we must invest now or pay far worse costs later?

My constituents—whether in Heaton or Horwich, Chew Moor or Chequerbent—need to know that the Government are on their side and that attempted public sector fraud will have consequences, no matter who you are or who you know. It is only by pursuing fraudsters tenaciously that we will be able to find the much-needed resources to support investment in critical infrastructure and ensure that we are as prepared as we can be, whether that is for the next pandemic, climate change, industrial sabotage or conflict.

The Minister has not mentioned climate change. Climate change is not a natural hazard; it is a human-made major risk.

Angela Eagle (Labour)

I agree, and it is important for the hon. Lady to understand that we are integrating climate change risks into our work. The Department for Environment, Food and Rural Affairs is the leading Department on work on climate adaptation, not mitigation. It is important that lead Departments can focus on the issue at hand, and DEFRA is doing adaptation.

Ellie Chowns (Green)

One of the key points that I tried to get across in my speech is that this has to be a whole-of-Government effort. DEFRA cannot put in place a strategy to adapt the health service to the reality of climate change. It cannot put in place a strategy to adapt our schools, our transport infrastructure or our energy infrastructure to the reality of climate change. Does the Minister not recognise that this has to be a whole-of-Government effort, and that it is not something that DEFRA can hold? That is precisely why we need a Cabinet Office Minister to lead on climate resilience.

Alicia Kearns (Conservative)

Since as early as 2013, when I was working with the Cabinet Office—specifically with the Joint Intelligence Organisation and others—climate change has been included in the matrix that it is required to plan for, respond to and seek to mitigate from a national security perspective. It is very much reflected in the national —I have forgotten the exact words, but it is the one that does not have an acronym. That is what happens when you work on something for too long. Climate change is in there and has been in there for a very long time, even way back when I was a civil servant.
